If I want to use the locate command on a Linux machine, I usually run sudo updatedb first to update the database. I can run the locate command on OS X 10.5 but I can't find updatedb. What's the corresponding updatedb for the mac?

We often require to find an equivalent text command for any GUI operation. Just as an example we click on a folder (say ABC) from the current directory in order to see the contents of that directory. The equivalent command for it to happen would be->

Code:cd ABC ls Now the thing is that we often don't know what that equivalent command will be. So I want to know that is there any way out to find it. What I want to do is that I shall perform any operation using mouse in the GUI mode(whatever operation it could be) and then I can see a log file to see what I actually did last(rather what the command would have been if I have worked in the text mode)...

I am teaching using an Ubuntu 10 server. The course stipulates the students use the mail command to send me assessment work, however I can't get mail to work (I did have to install it in the first place). After I end the message with a dot I get the message "send-mail: cannot open mail:25".

What is the equivalent of read -r (solaris command ) in Linux ? read utility in solaris will read a single line from standard input and -r option is used not to treat backslash () as an escape character .

I tried to run % mvdir earlier and it said command not found. I then ran a search for it and still not found.Is there a place I can download the script for the command, and is there any information I should know post-download to get it to work?

I write a script to read a file which is something like a pipe (or) queue , which shows the running status.In normal case, if i open this file with cat command, i have to use ctrl+c to exit this . What command shall i use to do the same inside a shell script ? I have tried ^C in my script , but it does not exit the process.

Is there any Linux equivalent to Windows Live Writer? I've got the Wordpress for iPhone app on my iPod and Windows Live Writer on Windows. These programs are much easier for stuff such as adding images than the web interface. Is there a similar program for Linux that works with self-hosted Wordpress blogs?

I'm pretty sure this is super simple, but I've searched and searched and for the life of me I can't find any info on how to limit the columns that display in the interactive top program with arguments passed from the command line. I recall seeing something formatted like this ...

~/top -f (kdx)

Which would only show the %CPU, UID, program name fields/columns. I'd like to display the results in a really narrow terminal window on the right side of my desktop.

When looking for a certain word or phrase in the man page of linux command, one can type '/' followed by the word/phrase to search for it. What I'd like to be able to do is to search for the next occurrence of the word/phrase without having to type it out again. Kinda like when you use 'ctrl+f' in a browser to search for a word, and then press 'enter' to find the next occurrence of that word.If this is possible to do, how do I do it?

I am trying to ssh into my server from the command-line without including the username in the url. I do not want it to send any username, as it currently takes the active account and sends that as user.ex:

ssh server.com -> (doesn't send default username)

instead of [URL] I would want to input username directly into the server, just like it is done using putty on windows. he wants to be prompted for a username, rather than having to provide one when connecting - but I don't really see the utility in such a thing. - birryree Sep 8 at 17:41

I use udhcp with some of my minimal installs. I've messed around with the code a bit when it wasn't working correctly - a few years ago. I will find time - I hope soonish - to figure out how to do a few other things with it.
